King Attalus III left his kingdom to Rome in his will, and a man claiming to be a royal bastard fought Rome for it

Attalus III, last king of Pergamon, died in 133 BC without children. His will left his kingdom and treasury to the Roman people. In Rome the tribune Tiberius Gracchus proposed using the treasure to fund his land reform, taking control of it from the Senate. Senators and their supporters killed Gracchus that year. In Asia Minor a man named Aristonicus claimed to be an illegitimate son of the earlier king Eumenes II and took up arms for the throne. He raised an army that included freed slaves and won early battles, killing the Roman consul Publius Licinius Crassus in 130 BC^†. Rome captured him in 129 BC and he was executed in Rome. The kingdom became the province of Asia, one of Rome's richest. The Attalid will was the first of several. Ptolemy Apion left Cyrenaica to Rome in 96 BC, and Nicomedes IV left Bithynia to Rome in 74 BC.
